Yoga Pose Coach
2nd place, Megathon 2024 — on-device pose correction from joint angles
2nd place at Megathon 2024, also Qualcomm-sponsored.
We built a human keypoint detector and turned it into a yoga instructor app. The app estimates body pose, computes the angles along pre-determined keypoint-to-keypoint edges, and compares them against the target pose — so it can tell you which joint is wrong and in which direction, then guide you through a sequence.
Like SnapGen a year later, it had to be deployed on the Qualcomm QIDK NPU, which was my first encounter with getting a model onto hardware that behaves nothing like a GPU.
